A new and novel way of capturing patient information at the point ofservice is provided. Such a system may be able to distinguish between aphysician voice and a patient's voice. The system may use a combinationof microphones. The first microphone may be in the external auditorycanal of the healthcare provider. It may be optimized to pick up the“Self-voice” of the healthcare provider. This has the distinct advantageof being acoustically isolated in the external canal of the healthcareprovider while providing the optimal environment for capturing the“self-voice” of the primary user. The external microphone may beoptimized to pick up the vocal sounds from the patient in the room. Indoing so, the healthcare user's microphone would be able to discern thedifference between the two voices based upon microphone inputs. Thisallows the optimized speech engine to segregate the two voice inputs.Such inputs can then be directly inputted into the patient record,stored in the selected position within the record as a voice file, orboth. In this fashion, the system may provide the ultimate inflexibility to rapidly and accurate capture the conversation between ahealthcare worker and patient, convert to text while at the same timeallowing for review or modification as needed. Such editing capabilityallows the user to have the ability to edit all aspects of the documentbefore their electronic signature.

According to one aspect, a system for voice dictation is provided. Thesystem includes an earpiece. The earpiece includes an earpiece housingsized to fit into an external auditory canal of a user and block theexternal auditory canal, a first microphone operatively connected to theearpiece housing and positioned to be isolated from ambient sound whenthe earpiece housing is fitted into the external auditory canal, asecond microphone operatively connected to earpiece housing andpositioned to sound external from the user, and a processor disposedwithin the earpiece housing and operatively connected to the firstmicrophone and the second microphone. The processor is adapted tocapture a first voice audio stream using at least the first microphone,the first voice audio stream associated with the user, and a secondvoice audio stream using at least the second microphone, the secondvoice audio stream associated with a person other than the user. Thesystem may also include a software application executing on a computingdevice which provides for receiving the first voice audio stream into afirst position of a record and receiving the second voice audio streaminto a second position of the record.

DETAILED DESCRIPTION

FIG. 1 illustrates one example of a system. As shown in FIG. 1 there areone or more earpieces 10 such as a left earpiece 12A and a rightearpiece 12B. Although multiple earpieces are shown, only a singleearpiece may be used. The earpieces 12A, 12B may be in operativecommunication with a computing device 2. The computing device 2 may be acomputer, a mobile device such as a phone or tablet, or other type ofcomputing device. There may be a display 4 associated with the computingdevice 2. A server 6 is also shown. The server 6 is in operativecommunication with a data store 8 such as a database. The server 6 maybe a cloud-based server, a physical server, a virtual server executingon a hardware platform, or other type of server.

FIG. 2 illustrates a set of earpieces 10 in greater detail. A leftearpiece 12A is housed within an earpiece housing 14A. The left earpiece12A includes an outward facing microphone 70A. The right earpiece 12B ishoused within an earpiece housing 14B. The right earpiece 12B includesan outward facing microphone 70B. The earpieces may be the earpieceswhich are commercially available from Bragi GmbH such as THE DASH.

FIG. 3 illustrates a block diagram of one of the earpieces 12. Theearpiece 12 has an earpiece housing 14. Disposed within the earpiecehousing is at least one processor 30. The processor 30 is operativelyconnected to at least one wireless transceiver 34 which may include aradio transceiver capable of communications using Bluetooth, BLE, Wi-Fi,or other type of radio communication. One or more external microphones70 and one or more internal microphones 71 are also operativelyconnected to the processor 30. In addition, a speaker 73 is operativelyconnected to the processor 30. Note that the external microphone(s) 70may be positioned to detect or capture voice streams associated with oneor more speakers other than the person wearing the earpiece (the user).The one or more internal microphones 71 may be, for example, positionedat or near the external auditory canal or mastoid bone of the user andmay provide for picking-up bone vibrations or are otherwise configuredto pick up frequency ranges associated with the person wearing theearpiece. In addition, there may be one or more inertial sensors 74present in the earpiece 12. The inertial sensor may include a gyroscope,accelerometer, or magnetometer. For example, the inertial sensor 74 maybe a 9-axis accelerometer which includes a 3-axis gyroscope, a 3-axisaccelerometer, and a 3-axis magnetometer.

FIG. 4 illustrates one example of a software application which includesa screen display 100. Various form fields 102, 106, 110 are shown. Inone embodiment, each time a different speaker (e.g. person) speaks, thesoftware application moves to the next form field. Each form field ispopulated with text acquired from conversion of voice information totext information. In addition, to this representation of the translatedtext, the underlying voice stream or voice recording may be played byselecting the corresponding play button 104, 108, 112. Thus, informationfrom multiple individuals may be collected. It is of further note, wherethe earpiece includes separate microphones for external users and theuser of the ear pieces, that separate voice streams may be captured evenwhen the user of the earpieces and another individual are talking at thesame time. It is to be further contemplated that there may be more oneother individual who is speaking who is within the environment of theuser.

Capturing and storing the voice streams or voice snippets andassociating these voice streams or voice snippets with the text mayprovide additional advantages. There is a complete record so that ifneed be the text information may be correctly later or date if it doesnot accurately match the voice snippet.

FIG. 5 illustrates another example of a software application that may beused. As shown in FIG. 5, there is a screen display 120 which may beassociated with a word processor document. The word processor may be aword processor such as Microsoft Word, the Microsoft Office Onlineversion of Microsoft Word, WordPerfect, TextMaker, Pages from Apple,Corel Write, Google Docs, or any other word processor. The wordprocessor software may execute on a local machine or on a remote machinesuch as available through cloud or web access. Functionality may bebuilt-into the word processor or may be provided as an add-in, as aconnected application, or otherwise.

As shown in FIG. 5, a transcript may be created which includes text frommultiple different speakers. As shown, each speaker may be identifiedsuch as “Speaker 1”, “Speaker 2.” Alternatively, each speaker may begiven a name. Also, instead of or in addition to identifying speakers inthis fashion, text associated with different speakers may be presentedin different colors of text, different fonts, or different styles. Asshown in FIG. 5, an icon may be shown associated with a mouse or othercontrol device. The mouse or other control device may be used to selecta portion of the text. When that portion of the text is selected, thecorresponding audio may be played. Thus, if there appears to be atranscription error in the text, a user may confirm whether there was atranscription error or not. Alternatively, a portion of text may beotherwise selected such as by selecting an icon associated with thatportion of the text. Thus, as shown a first speaker may make a firststatement 122, a second speaker may make a second statement 124, and thefirst speaker may make a third statement 126. A tooltip 130 is shownindicating that a user can choose to select text to listen tocorresponding audio.

FIG. 6 illustrates another example of a software application. FIG. 6illustrates a screen display 130 associated with an electronic medicalrecord (EMR), electronic health record (EHR), electronic patient record(EPR), or other type of medical record. In the context of a medicalrecord, it is contemplated that information entered into a medicalrecord may come from words dictated by a health care provider or frominformation obtained orally from a patient. The earpiece describedherein may be used to collect audio from both the health care provider(such as by using a bone conduction microphone) and from the patient(such as by using an external facing microphone). For example, as shownin FIG. 6 voice information associated with the reason for the visit, asspoken by a patient, may be input as text into form field 132 and arecording of the audio may be associated with this form field. Inaddition, voice information, as spoken by the health care provider, maybe input as text into form field 134 and a recording of the audio may beassociated with this form field. Although given as an example in thecontext of the medical field, any number of other situations may beappropriate where a transcript of an encounter is desired.

FIG. 7 illustrates another example of a screen display 140. As shown inFIG. 7, a transcript may be created which includes text from multipledifferent speakers. As shown, each speaker may be identified such as“Speaker 1”, “Speaker 2.” Alternatively, each speaker may be given aname. In addition to a transcript of text, the ear piece may includeother information sensed by the ear piece. For example, where the earpiece includes an inertial sensor, information associated with theinertial sensor or a characterization of information associated with theinertial sensor may be included. In this example, “Speaker 2” is wearingthe earpiece. The statement 142 made by Speaker 1 may be detected withan externally facing microphone of an earpiece worn by Speaker 2. Inresponse to statement 142, Speaker 2 may nod their head in agreement.This gesture or movement associated with the head nod may be detectedwith one or more inertial sensors of the earpiece. This head movement ora record of it may then be incorporated into the transcript. The recordof the head movement 146 may be shown in a manner distinct from thevoice transcript such as using different colors, fonts, or styles, suchas underlining, including in parentheses, or otherwise. In addition,additional information may be obtained by selecting the inserted textindicating that the nod occurred. The additional information may be inthe form of raw sensor data, or other characterization of the nod orother sensor data. Examples of different characterizations may includethe degree of the head nod or characterization of how pronounced thehead nod is. The characterizations may be quantitative or qualitative. Atooltip 148 may be shown indicating that a user may select thecontextual feedback to access this additional information. In additionto head nods, other gestures may also be detected. This may include ahead shaking movement, such as may be associated with a “NO.” Althoughgestures as detected with inertial sensors are one type of movementwhich may detected to provide contextual feedback, it is contemplatedthat other types of contextual feedback may be used such as may bedetected through physiological monitoring or otherwise. Other types ofsensors may also include image sensors. Where image sensors are used,the image sensors may be used to detect information from either theindividual wearing the earpiece or other wearable device or from others.Thus, records may be created for nonverbal information as a part of atranscript of a communication or as input into different fields within adocument or software application.

In another embodiment, a person is using the earpieces on a phone calland the voice of the person on the other side of the call is capturedand transcribed as opposed to capturing voice of a person through one ormore microphones on the ear piece. In yet another embodiment, aconversation may occur either in person or over a communication networkwith two or more individuals with at least two of the individualswearing earpieces so that contextual information from more than oneperson may be captured as a part of the conversation.

Therefore, methods and systems for voice dictation using one or moreearpieces have been shown and described.
